Jessica and Ashlee Simpson Attend Macy's Event | Pictures

Jessica Simpson and Ashlee Simpson made a cameo at the South Coast Plaza mall in Costa Mesa, CA, yesterday for a special event at Macy's. The Simpson sisters attended a meet-and-greet with fans on behalf of the Jessica Simpson's adults' and girls' collections. Both lines are part of Jessica's brand empire, and she enlisted Ashlee's help in designing the installment for girls. Work has been keeping Jess plenty busy lately. She's logged time on the set of Fashion Star and oversaw her brand's Spring '13 ad campaign. Despite the long hours, Jess has had plenty of time with her baby daughter, Maxwell. Their family fun included a costumed Halloween, in which Maxwell dressed as a chicken and a monkey.
